TO ALL WHGM IT MAY CONCEN:

Be it lrnown that I, JOSPlvI-L. REILLY, oi Chester, in the connty of Delaware,A and State of Pennsylvania, have invented' a new and improved Furnace-Door; and I. do. hereby declare that the following is a. i'ull,l clear, and exact description thereof, which will enable those skilled' in the "art to make and use th being had to the' accompanying drawings,i`orming part of this specification, in which- Figure v1 represents a front view of m.y improved furnace-door.

Figure 2'is an inverted horizontal section of the same, the plane of section being indicated by the line z z, fig. 1.

A Similar letters of reference -indicntecorresponding parts.

This invention relates to a new furnace-door for; marine boilers, and its object is to facilitate the firing of o same, reference `the furnace while the vessel labors in n. heavy sen.

The invention consists in the` use of n. latch, which is pivoted to the door, and which, when the door is opened, springs into n. catch that is provided onthe furnace-door frame or front of boiler, so that the door will remain open us long as required. v

A, in the drawing, represents o furnn-ce-door, of ordinary or suitable description, hinged to the furnacefront in the ordinary or suitable manner, Bis the latch pivoted to the front of the door, so that its two ends project beyond theisides ofthe door, as shown. When the door isclosed one end of thelatch B fits into a hook or catch, C, so as to hold the door closed, as in fig. 1. When the door is opened the other end of the latch B ts into a reccssn'hich is cut into-the lower face of a block, D, that projects from the front of the furnace or boiler, as shown, and the latch thus keeps the door open, as indicated by red lines in ligen-1 and 2. i

This invention will be of great advantage on all vess will not have to be held open by another person, As the bolt projects with 'its two ends beyond the desired to close` the door. It may be unnecessary to have that end which is to lock into the catch D project beyond thedonr, as the same object can be obtained if the end projects somewhat from the face of the door. The reeessp'in the block-D may be in any direction, so that the door may be held more or'less wide open.

Iclaim as new, and desire' to secure by Letters Patent-f 1. Providing a. fnrnace-door with a latch` B, which can be locked int ing the door open, substantially as herein shown and described.

`2. The bolt B of a fnrnace-door, when arranged as described, so that it serves to hold the door open and to keep it closed, substantially i'n the manner herein set forth.

which has heretofore been u. source of much inconvenience.

o u. catch, D, for the purpose of hold- JOSEPH L. REILLY.

els, as the furnace-door will remain open of itself, andY door, it will be easy to release it from the block- D when it is
